Exclamation point on Tunnel?

So, I just noticed that there’s an exclamation point on the entrance to the tunnel connected Takran and Vasek, but I can’t figure out why it’s there. I guess it’s not really a big deal, but I can’t figure out what it’s for and it’s bugging me! Lol help!

If you already went to the tunnel its pretty much just there to let you know you can still use it

Yeah but wouldnt that be normal? Maybe They forgot to code it away?

Ive been spending 4 hrs searching the way put to go to takran using the tunnel but still cant find it… Have you been there? Could you help me out what to do?please

It isn’t like you average dungeon which has only one way in/out. It’s a tunnel, i.e. it has both an entrance and an exit. You go down three floors and then you use the second staircase that you find to travel back up, then you’ll reach Takran
